Bees visit these flowers, like those of the Coryanthes, in order to gnaw the labellum; in doing this they inevitably touch a long, tapering, sensitive projection, or, as I have called it, the antenna. This antenna, when touched, transmits a sensation or vibration to a certain membrane which is instantly ruptured; this sets free a spring by which the pollen-mass is shot forth, like an arrow, in the right direction, and adheres by its viscid extremity to the back of the bee. The pollen-mass of the male plant (for the sexes are separate in this orchid) is thus carried to the flower of the female plant, where it is brought into contact with the stigma, which is viscid enough to break certain elastic threads, and retain the pollen, thus effecting fertilisation.<\/em><\/p>\n \u00a0<\/em><\/p>\n La estructura de la flor en otra orqu\u00eddea muy pr\u00f3xima, el Catasetum, es muy diferente, aunque sirve para el mismo fin, y es igualmente curiosa. Los himen\u00f3pteros visitan sus flores, como las de Coryanthes, para morder su labelo; al hacer esto, tocan inevitablemente un saliente largo, afilado y sensible, o antena, como lo he denominado. Esta antena, al ser tocada, transmite una sensaci\u00f3n o vibraci\u00f3n a cierta membrana, que se rompe instant\u00e1neamente; esto suelta un resorte, mediante el cual la masa de polen es lanzada en l\u00ednea recta como una flecha, y se pega por su extremidad, que es viscosa, el dorso del himen\u00f3ptero. Las masas de polen de la planta masculina -pues los sexos est\u00e1n separados de esta orqu\u00eddea- son transportadas de este modo a la planta femenina, donde se ponen en contacto con el estigma, que es lo bastante viscoso para romper unos hilos el\u00e1sticos, y, reteniendo el polen, se efect\u00faa la fecundaci\u00f3n.<\/em><\/p>\n \u00a0<\/em><\/p>\n Tras leer\u00a0 las adaptaciones de estas orqu\u00eddeas uno se pregunta: \u00bfC\u00f3mo puede alguien explicar esto mediante la supervivencia del m\u00e1s apto?
